In addition to whey protein isolate and whey protein concentrate, there is also whey protein hydrolysate. What is whey protein Hydrolysate? Whey Hydrolysate undertakes higher processing than either whey isolate or concentrate. It consequently is the highest quality protein but with this usually comes an increase in retail price.

Whey hydrolysate is easy on the digestive system and has a high absorption rate. The high absorption rate means it is the most effective whey to take either pre or post workout. The high protein content means only a small amount is needed, so please check individual manufacturers for dosages. Whey hydrolysate can be absorbed in anywhere between 10 and 30 minutes*. It is not really suitable for the ‘snack meal’ as it contains so little biologically active proteins (these are destroyed during the amount of processing hydrolysate undergoes.)

*Based on a serving in water on an empty stomach. Absorption rates can vary if taken on empty stomachs or with other delivery systems i.e. milk instead of water.
